Application inea May 9, 1914. serial No. 837,499.

To all wim/m it may concern:

Be it known that I, HANS C. IIALLUM, a citizen of the United States,residing at Keokuk, in the county of Lee and State of Iowa, haveinvented certain new and useful Improvements in Wrenches, of which thefollowing is a specification.

This invention relates to new and. useful improvements in wrenches, andhas for its principal object to provide a device which combines theadvantages of the ordinary type of spanner wrench with those of theadjustable j aw wrench.

Another object of the invention is to provide a Spanner wrench in whichthe jaws may be made to fit different size nuts without necessitatingthe use of screw or similar devices.

A further object of the invention is to provide a novel means foradjusting the jaws on the wrench to make the same of such size as to fitdifferent size nuts.

l/Vith these and other objects in view, the invention consists in thenovel combination and arrangement of parts which will be fully set forthin the following specification and accompanying drawings, in which,

Figure l is a side view in elevation of a wrench constructed inaccordance with this invention, portions thereof being broken away tomore clearly illustrate the details of construction, Fig. 2 is an endview thereof, and Fig. 3 is a detail perspective view of one of the jawadjusting members.

Referring now to the drawings by characters of reference the numeral ldesignates as an entirety the main body portion of a wrench havingformed at each end the enlargements 9.. These enlargements are providedwith the extensions 3 which are spaced from each other to form thenut-receiving chamber 4.

A suitable depression 5 is formed in one of the extensions 3 and isarranged to receive the lug carried by the filler member which will bemore fully hereinafter described.

An inwardly extending rectangular recess 6 is formed in the enlargement2 and is of such width as to extend for substantially half the distancebetween the arms 3. hereinbefore referred to. This rectangular recess 6extends in a plane parallel to the walls of the chamber 4 as clearlyillustrated in Fig. l, and one wall of this recess lies flush with theextension having the depression therein.

The iiller member hereinbefore referred to, which is best illustrated inFig. 3, and is designated generally by the numeral 7, preferablycomprises the rectangular body portion S having formed integraltherewith a suitable lug 9, which is arranged to seat within thedepression 5 when the filler member is in place. Each iller member isprovided with a similar depression l0 so that a number of such membersmay be arranged in coperative relation in order that the size of the nutreceiving chamber may be regulated.

In order to hold the filler members in place there is provided the leafspring 11 having the angular extension l2 which lies in a plane parallelto the bottom of the recess 6, hereinbefore described. The free end ofthis spring bears against the upper faces of the filler membershereinbefore described and thus prevents accidental displacementthereof.

It will beevident from the foregoing that in use when the nut receivingchamber 4 is too large to fit the nut properly a filler member such asthat illustrated in Fig. 3. may be inserted so that the end opposite theend carrying the lug 9 will project into the recess 6 and lie betweenthe free end of the spring 1l and the wall of the chamber 4 which isflush with the recess. The lugaed end is then raised so thatthefillermav be forced rearwardly into the chamber against the angularextension 12 of the spring until the lug comes in alinement with thedepression 5, at which time the lug is permitted to descend into thedepression. and in this position it will be evident that the spring 11will materiallv assist in holding the filler members in place.

lVhile in the foregoing there has been shown and described the preferredembodiment of this invention, it is to be understood that such changesmay be made in the combination and arrangement of parts as will fallwithin the spirit and scope of the invention as deiined in the appendedclaim.

Having thus described my invention, I claim:

A wrench comprising a body portion. an enlargement at cne end of thebodv portion, said enlargement being provided with a nut receivingchamber and having a recess communicating with the nut receivingchamber, the nut receiving Chamber also having a depression in one 4ofits walls, one wall' of the recess being Hush with one wall of the nutreceiving chamber, a spring within the re-4 cess, e filler memberarranged to extend into the recess between the spring and the oppositewall thereof, and a lug carried by the 10 opposite end of the fillermember and :1r-k

ranged to extend into the depression in the wall of the nut receivingchamber whereby the filler member is held from displacement.

In testimony whereof I aiiix my signature in presence of two witnesses.

HANS C. HALLUM.
